Adult Size: Length: ca. 10.0 -13.0 mm
Identifying features: Piezodorus lituratus is large shieldbug with two adult colour forms which are related to sexual maturity. Those emerging and mating in the spring are predominantly green, whereas the new generation appearing in the late summer have purple-red markings on the pronotum and corium. As in many other shieldbugs, this species frequently becomes darker prior to hibernation.
Habitat: Although often associated in in heathland, parks and gardens where gorse is present, larvae also feed on broom, dyer’s greenwood and other plants in the Genisteae, and have also been found on laburnum and clovers.
Adult: All year but are active late July until early June.
Larvae: June until early August feeding on the seed-pods of gorse, broom, dyer’s greenwood and other plants in the Genisteae; they have also been found on laburnum and clovers.
Young adults occur from August onwards and have red/purple markings, but their colouration gradually darkens prior to over-wintering.
Distribution: Common and widespread throughout Britain and Ireland, in many habitats where gorse is present. (3 records in North Merseyside).

This species could be confused with the Green Shieldbug (Palomena prasina), but Piezodorus lituratus has a different habitat and red antennae.
